Enhancements

• Ember Concurrency has been converted to a V2 Embroider Addon (#551)
• Added a Glint template registry
• (Not really an enhancement, but) users are encouraged to directly use a task's bound .perform method (and curry with fn helper if needed) rather than to use the classic perform helper, which doesn't really add much value anymore
• That said, all 3 of Ember's helpers, including perform are now directly importable within .gts/.gjs files.

Breaking Changes

• Ember Concurrency's Babel transform needs to be manually registered as a Babel plugin. See upgrade docs
